FIELD

This application relates to a family of compounds acting as opioidreceptor ligands. Such compounds may provide therapeutic benefit in thetreatment of pain.

BACKGROUND

Opioid receptors (ORs) mediate the actions of morphine and morphine-likeopioids, including most clinical analgesics. Three molecularly andpharmacologically distinct opioid receptor types have been described: δ,κ and μ. Furthermore, each type is believed to have sub-types. All threeof these opioid receptor types appear to share the same functionalmechanisms at a cellular level. For example, activation of the opioidreceptors causes inhibition of adenylate cyclase, and recruitsβ-arrestin.

When therapeutic doses of morphine are given to patients with pain, thepatients report that the pain is less intense, less discomforting, orentirely gone. In addition to experiencing relief of distress, somepatients experience euphoria. However, when morphine in a selectedpain-relieving dose is given to a pain-free individual, the experienceis not always pleasant; nausea is common, and vomiting may also occur.Drowsiness, inability to concentrate, difficulty in mentation, apathy,lessened physical activity, reduced visual acuity, and lethargy mayensue.

There is a continuing need for new OR modulators to be used asanalgesics. There is a further need for OR agonists as analgesics havingreduced side effects. There is a further need for OR agonists asanalgesics having reduced side effects for the treatment of pain, immunedysfunction, inflammation, esophageal reflux, neurological andpsychiatric conditions, urological and reproductive conditions,medicaments for drug and alcohol abuse, agents for treating gastritisand diarrhea, cardiovascular agents and/or agents for the treatment ofrespiratory diseases and cough.

Selected compounds described herein are agonists and antagonists ofOpioid Receptors (ORs). The ability of the compounds to stimulate ORmediated signaling may be measured using any assay known in the art todetect OR mediated signaling or OR activity, or the absence of suchsignaling/activity. “OR activity” refers to the ability of an OR totransduce a signal. Such activity can be measured, e.g., in aheterologous cell, by coupling an OR (or a chimeric OR) to a downstreameffector such as adenylate cyclase.

A “natural ligand-induced activity” as used herein, refers to activationof the OR by a natural ligand of the OR. Activity can be assessed usingany number of endpoints to measure OR activity.

Generally, assays for testing compounds that modulate OR-mediated signaltransduction include the determination of any parameter that isindirectly or directly under the influence of a OR, e.g., a functional,physical, or chemical effect.

Samples or assays comprising ORs that are treated with a potentialactivator, inhibitor, or modulator are compared to control sampleswithout the inhibitor, activator, or modulator to examine the extent ofinhibition. Control samples (untreated with inhibitors) are assigned arelative OR activity value of 100% Inhibition of an OR is achieved whenthe OR activity value relative to the control is about 80%, 50%, or 25%.Activation of an OR is achieved when the OR activity value relative tothe control (untreated with activators) is 110%, 150%, 200-500% (i.e.,two to five fold higher relative to the control) or, 1000-3000% orhigher.

The effects of the compounds upon the function of an OR can be measuredby examining any of the parameters described above. Any suitablephysiological change that affects OR activity can be used to assess theinfluence of a compound on the ORs and natural ligand-mediated ORactivity. When the functional consequences are determined using intactcells or animals, one can also measure a variety of effects such aschanges in intracellular second messengers such as cAMP.

Modulators of OR activity are tested using OR polypeptides as describedabove, either recombinant or naturally occurring. The protein can beisolated, expressed in a cell, expressed in a membrane derived from acell, expressed in tissue or in an animal. For example, neuronal cells,cells of the immune system, transformed cells, or membranes can be usedto test the GPCR polypeptides described above. Modulation is testedusing one of the in vitro or in vivo assays described herein. Signaltransduction can also be examined in vitro with soluble or solid statereactions, using a chimeric molecule such as an extracellular domain ofa receptor covalently linked to a heterologous signal transductiondomain, or a heterologous extracellular domain covalently linked to thetransmembrane and or cytoplasmic domain of a receptor. Furthermore,ligand-binding domains of the protein of interest can be used in vitroin soluble or solid state reactions to assay for ligand binding.

Ligand binding to an OR, a domain, or chimeric protein can be tested ina number of formats. Binding can be performed in solution, in a bilayermembrane, attached to a solid phase, in a lipid monolayer, or invesicles. Typically, in an assay described herein, the binding of thenatural ligand to its receptor is measured in the presence of acandidate modulator. Alternatively, the binding of the candidatemodulator may be measured in the presence of the natural ligand. Often,competitive assays that measure the ability of a compound to competewith binding of the natural ligand to the receptor are used. Binding canbe tested by measuring, e.g., changes in spectroscopic characteristics(e.g., fluorescence, absorbance, refractive index), hydrodynamic (e.g.,shape) changes, or changes in chromatographic or solubility properties.

Modulators may also be identified using assays involving β-arrestinrecruitment. β-arrestin serves as a regulatory protein that isdistributed throughout the cytoplasm in unactivated cells. Ligandbinding to an appropriate OR is associated with redistribution ofβ-arrestin from the cytoplasm to the cell surface, where it associateswith the OR. Thus, receptor activation and the effect of candidatemodulators on ligand-induced receptor activation, can be assessed bymonitoring β-arrestin recruitment to the cell surface. This isfrequently performed by transfecting a labeled β-arrestin fusion protein(e.g., β-arrestin-green fluorescent protein (GFP)) into cells andmonitoring its distribution using confocal microscopy (see, e.g.,Groarke et al., J. Biol. Chem. 274(33):23263 69 (1999)).

Another technology that can be used to evaluate OR-protein interactionsin living cells involves bioluminescence resonance energy transfer(BRET). A detailed discussion regarding BRET can be found in Kroeger etal., J. Biol. Chem., 276(16):12736 43 (2001).

Other assays can involve determining the activity of receptors which,when activated by ligand binding, result in a change in the level ofintracellular cyclic nucleotides, e.g., cAMP, by activating orinhibiting downstream effectors such as adenylate cyclase. Changes inintracellular cAMP can be measured using immunoassays. The methoddescribed in Offermanns & Simon, J. Biol. Chem. 270:15175 15180 (1995)may be used to determine the level of cAMP. Also, the method describedin Felley-Bosco et al., Am. J. Resp. Cell and Mol. Biol. 11:159 164(1994) may be used to determine the level of cGMP. Further, an assay kitfor measuring cAMP a is described in U.S. Pat. No. 4,115,538, hereinincorporated by reference.

Transcription levels can be measured to assess the effects of a testcompound on ligand-induced signal transduction. A host cell containingthe protein of interest is contacted with a test compound in thepresence of the natural ligand for a sufficient time to effect anyinteractions, and then the level of gene expression is measured. Theamount of time to effect such interactions may be empiricallydetermined, such as by running a time course and measuring the level oftranscription as a function of time. The amount of transcription may bemeasured by using any method known to those of skill in the art to besuitable. For example, mRNA expression of the protein of interest may bedetected using northern blots or their polypeptide products may beidentified using immunoassays. Alternatively, transcription based assaysusing reporter genes may be used as described in U.S. Pat. No.5,436,128, herein incorporated by reference. The reporter genes can be,e.g., chloramphenicol acetyltransferase, firefly luciferase, bacterialluciferase, β-galactosidase and alkaline phosphatase. Furthermore, theprotein of interest can be used as an indirect reporter via attachmentto a second reporter such as green fluorescent protein (see, e.g.,Mistili & Spector, Nature Biotechnology 15:961 964 (1997)).

The amount of transcription is then compared to the amount oftranscription in either the same cell in the absence of the testcompound, or it may be compared with the amount of transcription in asubstantially identical cell that lacks the protein of interest. Asubstantially identical cell may be derived from the same cells fromwhich the recombinant cell was prepared but which had not been modifiedby introduction of heterologous DNA. Any difference in the amount oftranscription indicates that the test compound has in some manneraltered the activity of the protein of interest.

Dosages

The compounds described herein may be administered to a patient attherapeutically effective doses to prevent, treat, or control one ormore diseases and disorders mediated, in whole or in part, by anOR-ligand interaction. Pharmaceutical compositions comprising one ormore of compounds described herein may be administered to a patient inan amount sufficient to elicit an effective protective or therapeuticresponse in the patient. An amount adequate to accomplish this isdefined as “therapeutically effective dose.” The dose will be determinedby the efficacy of the particular compound employed and the condition ofthe subject, as well as the body weight or surface area of the area tobe treated. The size of the dose also will be determined by theexistence, nature, and extent of any adverse effects that accompany theadministration of a particular compound or vector in a particularsubject.

Toxicity and therapeutic efficacy of such compounds can be determined bystandard pharmaceutical procedures in cell cultures or experimentalanimals, for example, by determining the LD50 (the dose lethal to 50% ofthe population) and the ED50 (the dose therapeutically effective in 50%of the population). The dose ratio between toxic and therapeutic effectsis the therapeutic index and can be expressed as the ratio, LD50/ED50.In some embodiments, compounds that exhibit large therapeutic indicesare used. While compounds that exhibit toxic side effects can be used,care should be taken to design a delivery system that targets suchcompounds to the site of affected tissue to minimize potential damage tonormal cells and, thereby, reduce side effects.

The data obtained from cell culture assays and animal studies can beused to formulate a dosage range for use in humans. In some embodiments,the dosage of such compounds lies within a range of circulatingconcentrations that include the ED50 with little or no toxicity. Thedosage can vary within this range depending upon the dosage formemployed and the route of administration. For any compound describedherein, the therapeutically effective dose can be estimated initiallyfrom cell culture assays. A dose can be formulated in animal models toachieve a circulating plasma concentration range that includes the IC50(the concentration of the test compound that achieves a half-maximalinhibition of symptoms) as determined in cell culture. Such informationcan be used to more accurately determine useful doses in humans. Levelsin plasma can be measured, for example, by high performance liquidchromatography (HPLC). In general, the dose equivalent of a modulator isfrom about 1 ng/kg to 10 mg/kg for a typical subject.

The amount and frequency of administration of the compounds describedherein and/or the pharmaceutically acceptable salts thereof will beregulated according to the judgment of the attending clinicianconsidering such factors as age, condition and size of the patient aswell as severity of the symptoms being treated. An ordinarily skilledphysician or veterinarian can readily determine and prescribe theeffective amount of the drug required to prevent, counter or arrest theprogress of the condition. In general it is contemplated that aneffective amount would be from 0.001 mg/kg to 10 mg/kg body weight, andin particular from 0.01 mg/kg to 1 mg/kg body weight. It may beappropriate to administer the required dose as two, three, four or moresub-doses at appropriate intervals throughout the day. Said sub-dosesmay be formulated as unit dosage forms, for example, containing 0.01 to500 mg, and in particular 0.1 mg to 200 mg of active ingredient per unitdosage form.

In some embodiments, the pharmaceutical preparation is in a unit dosageform. In such form, the preparation is subdivided into suitably sizedunit doses containing appropriate quantities of the active component,e.g., an effective amount to achieve the desired purpose. The quantityof active compound in a unit dose of preparation may be varied oradjusted from about 0.01 mg to about 1000 mg, from about 0.01 mg toabout 750 mg, from about 0.01 mg to about 500 mg, or from about 0.01 mgto about 250 mg, according to the particular application. The actualdosage employed may be varied depending upon the requirements of thepatient and the severity of the condition being treated. Determinationof the proper dosage regimen for a particular situation is within theskill of the art. For convenience, the total dosage may be divided andadministered in portions during the day as required.

In some embodiments, one or more compounds described herein areadministered with another compound. The administration may besequentially or concurrently.

Alternatively,2-[(9R)-9-(Pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]ethan-1-amine wasprepared by Raney-Nickel catalyzed hydrogenation.

An autoclave vessel was charged with2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro[4,5]decan-9-yl]acetonitrile andammonia (7N solution in methanol). The resulting solution was stirred atambient conditions for 15 minutes and treated with Raney 2800 Nickel,slurried in water. The vessel was pressurized to 30 psi with nitrogenand agitated briefly. The autoclave was vented and the nitrogen purgerepeated additional two times. The vessel was pressurized to 30 psi withhydrogen and agitated briefly. The vessel was vented and purged withhydrogen two additional times. The vessel was pressurized to 85-90 psiwith hydrogen and the mixture was warmed to 25-35° C. The internaltemperature was increased to 45-50° C. over 30-60 minutes. The reactionmixture was stirred at 45-50° C. for 3 days. The reaction was monitoredby HPLC. Once reaction was deemed complete, it was cooled to ambienttemperature and filtered through celite. The filter cake was washed withmethanol (2×). The combined filtrates were concentrated under reducedpressure at 40-45° C. The resulting residue was co-evaporated with EtOH(3×) and dried to a thick syrupy of2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]ethan-1-amine.

[(3-Methoxythiophen-2-yl)methyl]({2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]ethyl})amine

Into a vial were added2-[(9R)-9-(Pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]ethan-1-amine (500mg, 1.92 mmole), 18 mL CH2Cl2 and sodium sulfate (1.3 g, 9.6 mmole). The3-methoxythiophene-2-carboxaldehyde (354 mg, 2.4 mmole) was then added,and the misture was stirred overnight. NaBH4 (94 mg, 2.4 mmole) wasadded to the reaction mixture, stirred for 10 minutes, and then MeOH(6.0 mL) was added, stirred 1 h, and finally quenched with water. Theorganics were separated off and evaporated. The crude residue waspurified by a Gilson prep HPLC. The desired fractions collected andconcentrated and lyophilized. After lyophilization, residue waspartitioned between CH2Cl2 and 2N NaOH, and the organic layers werecollected. After solvent was concentrated to half of the volume, 1.0 eqof 1N HCl in Et2O was added, and majority of solvent evaporated underreduced pressure. The solid obtained was washed several times with Et2Oand dried to provide[(3-methoxythiophen-2-yl)methyl]({2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro[4.5]decan-9-yl]ethyl})aminemonohydrochloride (336 mg, 41% yield, m/z 387.0 [M+H]+ observed) as awhite solid. The NMR for Compound 140 is described herein.

Example 16 Biological Example Procedure for the Testing forAntinociception

The hot plate assay is adapted from the procedure originally describedby O'Callaghan and Holtzman (JPET, 192, 497, 1975) and is commonly usedto determine the potential analgesic efficacy of opioid agonists. Theantinociceptive effect of the composition(s) described herein in the hotplate is expressed in % MPE (Maximum Possible Effect).

Rats (175-250 g) or mice (20-30 g) acclimated to the vivarium for atleast 48 hr prior to behavioral testing. Test drugs were administered bythe subcutaneous (SC) route. Animals were placed on the hot plate, whichthe temperature was set at 50-56° C., depending on the in vitro potencyof the compound. A cutoff time of 30-60 seconds was used depending onthe temperature of the hot plate so that the paws of the animaldisplaying analgesia, was not damaged by the heat stimulus. The cutofftime was considered a 100% response to the thermal insult. Prior to drugtreatment, each animal was tested to determine the baseline response.Thirty minutes after drug administration, animals were re-tested. Doseresponse experiments were performed to evaluate the potency of the testcompound when various doses were administered at the point when maximalanalgesia is observed.

The % MPE was calculated according to the following formula: %MPE=[(Post drug latency−baseline latency)/(60 or 30−baselinelatency)]×100

ED₅₀ values were calculated from the mean % MPE values for each groupusing log dose-response curves by least-squares regression analysis.

TABLE 4 COMPOUND ED50 or % MPE Morphine 3.8 mg/kg SC Compound 81 100% at10 mg/kg SC Compound 122 1.1 mg/kg SC Compound 28 1.2 mg/kg SC Compound145 5.9 mg/kg SC

Results are shown in Table 4. Naïve or control mice typically exhibitreaction times in the hot plate from 10-15 seconds. The ED50 formorphine in the mouse hot plate was 3.8 mg/kg with full efficacyobserved at a dose of 10 mg/kg SC. For comparison, Compound 122 andCompound 28 produced potent efficacy with an ED50 of 1.1 and 1.2 mg/kgSC, respectively. These results demonstrate that Compound 122 andCompound 28 produced a more robust analgesic effect in the mouse hotplate assay compared to morphine.

One or more compounds will be administered in dosage range from 0.15 mgto 4 mg to human subject. The compound(s) will be administered as acontinuous infusion over one hour. The dose may be escalated as deemedappropriate to obtain pain relief. Dose escalation will usually notexceed 5-fold as compared to the previous dose. Dosage amounts, however,may be repeated or decreased as deemed appropriate. The subjects will betested for their ability to withstand or not appreciate pain as comparedto a control (placebo) group.

The cold pain test has been shown to be a reproducible and sensitivemeasure of the effect of opiates and other centrally acting drugs (Van Fand Rolan P E. The utility of the cold pain test to measure analgesiafrom intravenous morphine. Br. J. Clin. Pharmacol. 1996; 42: 663-664;Posner J. Pain Models in Healthy Volunteers. In: Nimmo W S, Tucker G,eds. Clinical Measurement in Drug Evaluation. 1991, Wolfe PublishingLimited, UK.; Wotherspoon H A, Kenny G N C, McArdle C S. AnalgesicEfficacy of Controlled-Release DihydroCodeine. Anaesthesia 1991; 46:915-917.; Lamb R J, Mercer A J, Posner J. The effect of lamotrigine (300mg) and dipipanone (4 mg and 8 mg), alone and in combination, on thecold-pain test in healthy volunteers. Br. J. Clin. Pharmacol. 1994; 39:539-588P.). In the test a subject's hand is immersed in cold waterchilled to a range of 1 to 3° C. The initial sensation of cold isreplaced by a deep burning discomfort in the hand which is mediated bynociceptors in veins. The discomfort gradually builds to a plateau overapproximately 90 seconds and then either persists or decreases slightly.The stimulus is easily controlled and the response is reproducible. Thetechnique has been shown to be sensitive to different doses of analgesicdrugs.

During the cold pain test, the subject will sit down and place his/hernon-dominant hand into a stirred, thermostatically controlled water bathat about 2° C. With the other hand the subject can adjust a visualanalogue scale on a computer screen using the arrow keys on the keypad.The scale is labelled “no pain” at one end and “maximum pain” at theother end. The pointer will initially be at the “no pain” end and thesubject will move the pointer across the line to rate their feelingscontinuously over the test period. At the end of 2 minutes the computerwill automatically instruct the subject to remove his/her hand which canthen be dried. The cold pain test has been used extensively in healthyvolunteer studies and is non-invasive.

It is expected that the administration of the compound(s) will enablethe human subject to feel no pain or less pain as compared to thecontrol group.
